Roofing in Franktown, CO

Franktown is unincorporated, so every roofing permit, inspection, and code question for a Franktown address runs through the Douglas County Building Division out of Castle Rock. We plan Franktown reroofs around that county process: when a permit is actually required, how many layers the county allows, what triggers ice-barrier underlayment, and which roof types need a mid-roof inspection before the covering goes on.

When a Franktown Reroof Needs a Permit

Douglas County requires a roofing permit for residential reroofing and repair, with one narrow exception: minor repairs or replacement of less than one roofing square, meaning under 100 square feet, do not require a permit. Anything at or above that one-square threshold needs a permit, and a house with more than one roofed structure, such as a detached garage or a barn, needs a separate roofing permit for each structure.

For straightforward reroofs, Douglas County allows a basic residential roofing permit to be submitted online when the existing roof is asphalt composition, masonite-type product, or metal, and the replacement roof is asphalt composition or metal. Tile, slate, stone-coated, and other specialty systems fall outside that online path and go through the standard submittal process instead.

Tear-Off and the One-Layer Rule

Douglas County requires roof replacement to remove existing roof coverings down to the deck rather than building up multiple layers. The county allows only one layer of asphalt shingles: an asphalt-shingle roof cannot be overlaid with a second layer of asphalt shingles. We plan every Franktown reroof as a full tear-off to the deck, not a layer-over-layer shortcut, so the finished roof meets that rule regardless of what is currently on the house.

Tearing off to the deck also gives us a look at the sheathing before anything new goes down. Soft spots, old leaks, or fastener damage found at that stage get addressed before underlayment and covering go on, rather than getting sealed in behind a new roof.

Ice Barrier Depends on Elevation, Not Assumption

Douglas County ties ice-barrier underlayment at the eaves to elevation: it applies where the structure sits above 7,000 feet USGS elevation, and underlayment generally must comply with the applicable IRC or IBC underlayment section. Franktown itself sits at roughly 6,198 feet, below that 7,000-foot line, so the county’s elevation trigger would not automatically apply to a typical Franktown lot. Elevation varies across individual parcels in this part of Douglas County, though, so we do not assume a number from the community’s general elevation alone; we confirm the specific site elevation and the current ice-barrier requirement with the Building Division before finalizing the underlayment plan, and we follow the shingle manufacturer’s own underlayment instructions regardless of what the county requires as a floor.

Drip Edge and Inspection Points

Drip edge on a Franktown reroof is sized to the county’s minimum: 4 inches by 2 inches at the eaves and 2 inches by 1 inch, or D-style edge metal, at the rakes. Asphalt and composition roofs get a drip-edge inspection as part of the process, and a final inspection is required for every roofing permit the county issues, regardless of roof type.

Tile, slate, stone-coated, steel, and any system that uses battens carry one more step: a mid-roof inspection, done once the roof is roughly a quarter to half complete, after felt, flashing, and battens are down but before the final covering closes everything up. Standing-seam and standard asphalt systems do not carry that extra inspection. We build the mid-roof step into the schedule for any batten-based system so the county can see what is about to be covered.

A Code-Edition Detail Worth Confirming

Douglas County’s own roofing permit materials reference inspection to the 2021 International Codes, while the county’s separate Adopted Building Codes page states the current edition is the 2024 IRC and IBC, with amendments effective July 1, 2026. That is the same kind of edition mismatch we have flagged on other Franktown project types, and we treat the Adopted Building Codes page as the authoritative one. Rather than build a roof plan around whichever edition happens to be easiest to find, we confirm the current adopted edition and effective date with the Building Division before ordering underlayment and flashing that need to match a specific code section.

Wildfire-Resistant Roofing in the Franktown Area

The Colorado State Forest Service’s Franktown Field Office identifies fire-resistant roofing, siding, and porch materials as one of the two primary factors in whether a home survives a wildfire, and recommends a Class A rated roofing material for homes in or near forests or grasslands, while steering clear of wood or shake shingles. That is CSFS education guidance rather than a numeric Douglas County ordinance we can cite for a specific address, so we do not claim a blanket county roofing-material mandate here. Where a Franktown parcel sits in a wildland-urban interface area under the county’s Wildfire Resiliency Code, we confirm the applicable material standard for that address with the Building Division before locking in a shingle or roofing system.

How We Sequence a Franktown Reroof

We start by confirming whether the scope crosses the one-square permit threshold, checking the site’s elevation and manufacturer underlayment requirements, and confirming the current adopted code edition with the county. Roofing itself is its own contractor-registration classification with Douglas County, and we confirm current registration status for the crew before filing.

Once the permit is issued, tear-off exposes the deck for a condition check, underlayment goes down according to the confirmed ice-barrier and manufacturer requirements, and drip edge is installed to the county’s minimum sizing. For tile, slate, stone-coated, or batten-based systems, we schedule the mid-roof inspection before the final covering goes on; for standard asphalt or standing-seam systems, the drip-edge check and final inspection close out the permit. We do not cover felt, flashing, or battens on an inspected system until that inspection point has been requested and met.

Common Questions

Does every Franktown reroof need a Douglas County permit?
Almost always, yes. Douglas County requires a permit for residential reroofing except for minor repairs or replacement under one roofing square, which is 100 square feet. Anything at or above that needs a permit, and each roofed structure on the property needs its own.

How many layers of shingles does the county allow?
One. Douglas County requires removal of existing roof coverings down to the deck and does not allow an asphalt-shingle roof to be overlaid with a second layer of asphalt shingles.

Will my Franktown roof need ice-barrier underlayment?
Douglas County’s ice-barrier trigger is tied to an elevation above 7,000 feet. Franktown’s general elevation is below that line, but elevation varies by parcel, so we confirm the specific site elevation and current requirement with the Building Division before finalizing underlayment, and we also follow the shingle manufacturer’s own instructions.

When does a mid-roof inspection apply?
Only for tile, slate, stone-coated, steel, or any roofing system that uses battens, performed once the roof is roughly 25 to 50 percent complete. Standard asphalt shingle and standing-seam metal roofs do not require that extra inspection, but every roofing permit still requires a final inspection.
